The Transportation and Development Institute of the American
Society of Civil Engineers (T&DI/ASCE) recently announced it will conduct a public comment period on Part Two of its revised Automated People Mover (APM) standard (ASCE 21). In order to expedite the approval and release process, as well as to facilitate ease of use, the standard has been divided into four parts. Part Two includes: scope, contents, references, definitions, vehicles, propulsion and breaking.

The standard establishes minimum requirements for the design, construction, operation and maintenance of APM systems, and is used in the safety certification process. The public comment period for Part Two of the standard will be held from July 15, 2007 to August 29, 2007.
